8. Maturation
CHANGES & CHALLENGES
CHANGES & CHALLENGES FROM 3-STREAM PROGRAM
ECO360
CHANGES & CHALLENGES
Cleaner feedstock is not without challenges
Less contamination in Organics stream led to increased
feedstock density and moisture content
As feedstock changes, the compost recipe changes too
ECO360
CHANGES & CHALLENGES
Overs reuse
Overs from the second screening (1 1/4 inches) are
matured and screened to capture as much material as
possible.
Overs from this and the final screening process are used
as alternate daily cover on our landfill.
ECO360
CHANGES & CHALLENGES
New screen for cured and matured
compost down to 1/4 inch
Removes glass
Meets CCME Category A
standards
There are operational challenges
to meeting this goal with
municipal waste feedstock
LOOKING AHEAD
POSSIBLE FUTURE IMPROVEMENTS
ECO360
LOOKING AHEAD
Looking for markets and getting guidance from stakeholders
on preferred end-uses for our compost.
Potential elimination of front-end processing in Compost
Plant.
